Hi Mikhail,
I don't see the matches `searcher.matches(topDocs.scoreDocs[i].doc,
"fieldName", query);` method exposed. I'm using lucene core 8.11.2 and
currently I cannot upgrade to 9.0.0 or later.
Any ideas? Which API version are you referring to?
Thanks.
Ned

Hi Ned.
It's about
TopDocs topDocs = searcher.search(query, 10);
for (int i = 0; i < topDocs.scoreDocs.length; i++) {
MatchesIterator matches = searcher.matches(topDocs.scoreDocs[i].
doc, "fieldName", query);
while (matches.next()) { ...
This is (almost) how highlighters (like
